Weather Forecasting
Weather Forecasting: _ Figure above shows overview of modern weather forecasting tools including satellites, radar systems, and computer models. ______ “A change in the weather is sufficient to recreate the world and ourselves.” ― Marcel Proust “It only takes one flap of a butterfly’s wings to set off a tornado on the other side of the world.” — Edward Lorenz ______ Section-1 Prologue: Since the dawn of human existence, the sky has been our grand stage.

This combination of opposing forces can create winds and result in the formation of storm clouds. Storms generally lead to significant negative impacts to lives and property. The vertical wind shear in thunderstorm can cause airplane crashes. Severe weather is also responsible for plenty of helicopter crashes, and delay launch of space shuttles. There are various types of storms including tropical […]
